A mild highly contagious virus infection, mainly of childhood, causing enlargement of lymph nodes in the neck and a widespread pink rash. The disease is spread by close contact with a patient. After an incubation period of 2–3 weeks a headache, sore throat, and slight fever develop, followed by swelling and soreness of the neck and the eruption of a rash of minute pink spots, spreading from the face and neck to the rest of the body. The spots disappear within seven days but the patient remains infectious for a further 3–4 days. An infection usually confers immunity. As German measles can cause fetal malformations during early pregnancy, girls should be immunized against the disease before puberty. Most children now receive immunization via the MMR vaccine in their second year. Medical name: rubella. Compare scarlet fever.
